The TFTR Neutral Beam Performance Database

The Tokamak Fusion Test Reactor (TFTR) Neutral Beam Injection System has been in operation since 1984, providing neutral beam heating to TFTR experiments. A database development effort has resulted in a comprehensive system capable of a variety of applications. The NB database stores information extracted from programs which provide operator feedback in the NB software event cycle. A powerful and flexible interactive plotting program is available to display results. A shot logger provides the global ability to set a flag in the performance database to describe the basic quality of the shot.
